Man-machine cooperation experimental platform for production scheduling

Measure the efficiency of planning and scheduling important indicator of the production scheduling for large-scale problem, which is especially important. When the device when the total number,stivali ugg, even a few percentage points difference, the plant will be a great benefit for the different, and so, for large-scale manufacturing enterprises, equipment utilization is an important indicator of deciding the fate of this argument is also But points, therefore, be used to evaluate the merits of the assessment indicators scheduling scheme also makes sense. Based on this idea, the shop scheduling assessment attributed to the following three indicators: the program's maximum extension of the number of days, the average extension of punishment, the average equipment utilization rate,ugg boots günstig, which average extension penalty is based on the maximum extension of the number of days and the resulting index is the largest extension of the right of the number of days multiplied by the value received, the value of and the delivery time requirements through the program to set the level. Through these three evaluation indicators for automatic, manual produced by an objective assessment of the various scheduling options. 3 instances of a more complex advanced scheduling experiment to illustrate the process of man-machine cooperation. Experimenter for the production of a 10 part task scheduling, the experimenter's task is to put 10 parts of 87 to 39 sets of different work arrangements of equipment for processing, and as much as possible to meet all parts of the delivery, improve equipment utilization. Automatic scheduling rules for scheduling by the machine for a time after the task Gantt chart shown in Figure 3. Mouth machine scheduling result in Figure 3 the upper half of Figure 3, a time for the task Gantt chart, lower into a time machine Gantt chart. Figure 3 Task Gantt chart can be a time of 56 see Industrial Engineering Volume 11, part Partl7 the first nine processes is beyond the Pa ~ 17 delivery (separate red process that delayed the process), by the dispatcher on Scheduling analysis of the results of manually scheduling, will affect the delivery of the Partl2 Partl7 the first seven processes processing equipment replacement, scheduling result shown in Figure 4. It can be seen from Figure 4, Pa ~ ff completion date greater than the results of the machine ahead of schedule, scheduling, evaluation results also show that the maximum extension of the program in Figure 4 the number of days,tory burch, the average extension of punishment, an average of three indicators of capacity utilization should be significantly better solutions in Figure 3. 4 Conclusion The results of Figure 4, with the ultimate scheduling application and development of computer technology, the use of computer-aided production scheduling technology is increasingly used in the manufacturing process to shorten the time production scheduling, resource utilization and improve balance Science and management purposes. Compared with the previous simple algorithm to solve the scheduling problem by the computer than the idea of using man-machine cooperative scheduling and the experimental method can combine the advantages of the computer, play a complementary role. Man-machine cooperation experiments with production scheduling heuristic scheduling techniques and man-machine cooperation in production technology to the experimenter on the complexity of scheduling problems have some perceptual knowledge, experience in production scheduling NP problem, experiments can be developed through the scheduling experiment production scheduling to possess the ability to develop their creative thinking. Because of the complexity of the human brain and memory awareness of the problem is limited, so use of the experimental platform for testing human brain to solve complex problems and cognitive ability to further define the problem in dealing with complicated scheduling, division of labor is the next man and machine The main work.
